Form I-9, Employment Eligibility Verification

What is Form I-9, Employment Eligibility Verification?

The Form I-9, Employment Eligibility Verification, is issued by the United States Citizenship and Immigration Services (USCIS) and must be used by the employer to verify an employee’s identity and to establish work authorization as evidence they are authorized to be employed and paid wages, regardless of citizenship or immigration status.

The Immigration Reform and Control Act of 1986 requires employers to hire only persons who may legally work in the United States-which are:

  • A citizen of the United States
  • A noncitizen national of the United States   
    • Defined as persons born in American Samoa, certain former citizens of the former Trust Territory of the Pacific Islands and certain children of noncitizen nationals born abroad)
  • A lawful permanent resident
    • Defined as any person who is not a U.S. citizen and who resides in the U.S. under legally recognized and lawfully recorded permanent residence as an immigrant.  The term “lawful permanent resident” includes condition residents.  (Issued a green card)
  • An alien authorized to work
    • Defined as persons, not a citizen or national of the U.S. or a lawful permanent resident, but authorized to work in the U.S. (examples: F-1 students, J-1 exchange visitors, H-1B, O-1, issued an Employment Authorization Document or I-766 EAD.

Purdue University does not discriminate against individuals on the basis of nation origin or citizenship.
